bit 15-8
bit 7-4
bit 3-0
Unimplemented: Read as ‘0’
YRTEN3:YRTEN0: Binary Coded Decimal Value of Year’s Tens Digit; Contains a value from 0 to 9
YRONE3:YRONE0: Binary Coded Decimal Value of Year’s Ones Digit; Contains a value from 0 to 9
Note 1: A write to the YEAR register is only allowed when RTCWREN = 1.
Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
